What is 'MR1' or 'MRORDERID' - in orders and on store?

When testing Monk offers, you may encounter situations where an 'mr1' sign is visible along with Monk's discounted product on the cart or see an 'mrORDERID' in 'Additional details' in your Shopify order.

What does mrORDERID indicate in Orders section in Shopify?

In the Shopify order section, the app includes an 'mrOrder ID' under the 'Additional details' section (top right) for backend tracking, attribution and analytics purposes. This ID is used to identify the customers who took actions like viewing the offer/widget, add to cart and order completed and link them back to the respective offers configures inside the app.

Please note that the 'mrOrder ID' is a permanent identifier and removing it will result in in-app anlaytics not working. Your customers will not see this and is only for internal purposes.

What does mr1 sign indicate on website?

The identifier _mr1 is added to products to indicate that they originate from our app and is used for analytics & tracking purposes. As per Shopify guidelines, this should be hidden by the theme by default and should not be visible to customers. However, on occasion, it may appear on the storefront as well. If this happens, our technical team can remove it, provided we have collaborator access or if you have a developer who can hide the same, kindly do so. You can use the code mentioned below to hide it.

Most themes automatically hide line item properties that are not useful for customers. If your theme does not do this, you can hide them manually with a small update. Open the file that contains the cart drawer or the cart page markup. Then find the section where the cart items are rendered and add the following lines of code there.

{% assign first_character_in_key = p.first | truncate: 1, '' %}
 {% unless p.last == blank or first_character_in_key == '_' %}

The step should be resulted like this:

 {% assign property_size = item.properties | size %}
 {% if property_size > 0 %}
 {% for p in item.properties %}
 {% assign first_character_in_key = p.first | truncate: 1, '' %}
 {% unless p.last == blank or first_character_in_key == '_' %}
 {{ p.first }}:
 {% if p.last contains '/uploads/' %}
 <a href="/%7B%7B%20p.last%20%7D%7D">{{ p.last | split: '/' | last }}</a>
 {% else %}
 {{ p.last }}
 {% endif %}
 {% endunless %}
 {% endfor %}
 {% endif %}

Above code checks all the custom properties of a product present in the cart. It only shows the details that are useful and hides anything that starts with an underscore which results in “_mr:1” being hidden from the customer.
